I’d imagine most “Internet vultures” know about THQ’s Metro:2033 giveaway on Facebook. THQ is currently promoting their new Metro game, Last Light (coming March 2013), by doing a December Metro:2033 giveaway on Facebook. If you don’t already own Metro 2033, head over to Metro’s Facebook page and grab your Steam code. All you need to do is like the page and redeem your free key.
